Abstract
La présente invention concerne un procédé d'identification d'un type de filtre médical, d'une classe de filtres ou d'une caractéristique d'un filtre médical, le filtre ayant au moins un premier compartiment de filtre et un second compartiment de filtre, qui sont séparés l'un de l'autre par un milieu filtrant. Le procédé comprend l'étape consistant à générer une pression dans un fluide sur un premier côté du milieu filtrant d'un filtre au moyen d'une première source de pression, en conséquence de quoi le filtre est soumis à une pression. Le procédé comprend en outre l'étape consistant à mesurer au cours du temps la courbe de pression sur le premier côté du milieu filtrant, sous la forme d'une première courbe de pression (1000) au moyen d'un premier capteur de pression (59) disposé entre la première source de pression et le filtre, ainsi que la courbe de pression sur le second côté du milieu filtrant, en tant que seconde courbe de pression (2000), au moyen d'un second capteur de pression (73). Le procédé comprend en outre l'étape consistant à évaluer à la fois la première courbe de pression (1000) et la seconde courbe de pression (2000) de manière à obtenir un résultat d'évaluation (3000, 4000), et l'étape consistant à attribuer au filtre médical, soumis à la pression, un type de filtre ou une classe de filtres ou à identifier une caractéristique du filtre médical.
